The quantity of waste generated grows and can cause many problems to human health and the environment. Recently, increased the discussions around the management of chemical waste in laboratories for teaching and research in Brazil, with that, details emerged of how this waste could provide occupational risks, besides offering damage to the environment. Hence, the plan for managing waste to the Institute of Chemistry of the Federal University of Goiás (IQ/UFG) was idealized. At work diagnoses and predictions for each stage of waste management were executed simultaneously, in a horizon of five years of the project. We raised the chemicals and materials used and the waste-generating activities, and then identified, quantified and ranked all waste generated. The diagnosis and prognosis of segregation, minimization, packaging, storage, collection, transportation, treatment and final disposal of waste generated were prepared. The results indicated that some materials were purchased in excess and many reagents are inadequately stored in the laboratories. The management at IQ/UFG is worrying, because there is no treatment and appropriate place for the storage of waste. 900 kg of common waste and 600 kg of chemical waste are generated per year. The chromatographic analyses are the activities that generate more chemical waste and administrative work is the activity that generates more common waste. Most of the chemical waste is of class I and flammable waste represents the greater percentage. Most of the common waste is paper and cardboard. It was proposed to build a shelter for the chemical waste and the acquisition of other containers for common waste. The chemical waste will be incinerated but waste containing mercury and cyanide, which will be forwarded to a hazardous waste landfill. The common recyclable waste will be transported to recycling cooperatives and non-recyclable waste will be sent to the landfill.
